The study demonstrates that Sputnik V neutralizes the Omicron variant by inducing robust antibody response associated with high levels of protection.
Gamaleya National Research Center of Epidemiology and Microbiology on Wednesday said that Sputnik V demonstrated strong protection against Omicron variant of COVID-19.
A comparative study conducted at the Italian Spallanzani Institute, the Italian research institute for infectious diseases, by a joint Italian-Russian team of researchers representing the Institute and the Gamaleya Center show that the Sputnik V coronavirus vaccine demonstrates higher titers of virus-neutralizing antibodies to Omicron (B.1.1.529) variant than 2 doses of Pfizer vaccine (2.1 times higher in total and 2.6 times higher 3 months after vaccination), Gamaleya Center said in a statement.
The study was published in an article by a team of 12 Italian and 10 Russian scientists led by Francesco Vaia, Director of the Spallanzani Institute and Alexander Gintsburg, Director of the Gamaleya Center.
According to the findings, the Sputnik vaccine provides for eliciting high titers of virus neutralizing antibodies to Omicron variant. Fast-spreading Omicron sub-variants BA.4 and BA.5 are currently causing surges of coronavirus cases in the United States, South Africa and 70 other countries.
